Utility - Promisify

promisify()

Promisify is a function that enables you to run your async validations as a Javascript Promise. This can be useful when running async validations on the server, or when you do not need the partial validation results.

The Promise is resolved when all tests finish running.

Usage

promisify() accepts a validation suite declaration, and returns a function that when called, returns a Promise.

import { create, test, skipWhen } from "vest";
import promisify from "vest/promisify";

const suite = promisify(
  create((data) => {
    test("email", "The email already exists", () => doesEmailExist(data.email));
    test("username", "The username already exists", () =>
      doesUsernameExist(data.username)
    );
  })
);

suite(data).then((res) => {
  if(res.hasErrors("email")) {
    /* ... */
  });

  if(res.hasErrors("username")) {
    /* ... */
  });
});
